Molecular Imaging

Nuclear imaging, also called molecular imaging, includes positron emission computed tomography (PET) and single photon emission computed tomography (SPECT) imaging. This section includes radiopharmaceuticals and tracers, PET-CT, SPECT-CT, and PET-MRI. Molecular imaging includes the field of nuclear medicine, which uses very small amounts of radioactive materials, or radiopharmaceuticals, to diagnose and treat disease.

Total-body dynamic 18F-FDG PET imaging with the uEXPLORER scanner allows us to monitor the spatiotemporal distribution of glucose concentration in metastatic tumors in the entire body (a). As compared to a typical clinical standardized uptake value image (b), the parametric image of FDG influx rate (Ki) can achieve higher lesion-to-background (e.g., the liver) contrast. In addition to glucose metabolism imaging by Ki, total-body dynamic PET also enables multiparametric characterization of tumors and organs
